Question

why nucleophilicity increases down the group​

Answer 1

Answer:

The more available the electrons, the more nucleophilic the system. ... Within a group in the periodic table, increasing polarisation of the nucleophile as you go down a group enhances the ability to form the new C-X bond and increases the nucleophilicity, so I- > Br- > Cl- > F-.

Answer 2

Hi buddy

Explanation:

Nucleophilicity

Since a nucleophile is a species that is donating a pair of electrons, it’s reasonable to expect that its ability to donate electrons will increase as it becomes more electron rich, and decrease as it becomes more electron poor, right? So as electron density increases, so does nucleophilicity

Factors affecting the nucleophilicity

1) Atomic Size

2) Electronegativity

3) Steric hindrance ( Bulkiness )

4) Choice of solvent

5) Charge ( Atom's Electron density )
